[Xen-ia64-devel] [Patch] Stop all cpus at panic time (take 2)

[Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>]

Hi,

Current panic() of hypervisor doesn't stop all cpus.
So domains can work after hypervisor panic.
(but this issue happens at only using noreboot option)
If dom0 works after Hypervisor panic,
the system may get a serious problem.

This patch fix the issue.

Changelog:
 - I choosed cpu_halt() to stop other cpus by smp_send_stop().
   I think it should work fine for kexec.
   machine_halt() is only spinloop for leaving the panic CallTrace.
   What do you think about it, Horms and Alex?

Signed-off-by: Akio Takebe <takebe_akio@xxxxxxxxxxxxxx>

Best Regards,

Akio Takebe
